Q @www posed portions of the plate between the strips 18 and 19 may be covered with opaque paper or other similar material. The negative is moved transversely of the irame and prints are Vtakenin succession. VVh'en a row has beenmade the negative is shifted longitudinally of the frame and another row' is printed. v

Instead of shifting the members 18 and 19 by hand it may be done by means of a screw mechanism such as that shown at 22 in Fig. 9. This screw as will be -observed passes through a member 17k similar to the member 17 in Fig. 8. The screw is provided with'a handle 23 and by turning this handle the frame members 18 and 19 bearing the negative 5 may be shifted at will over the plate 2. l
